Trouble with Plane Bearing Selection

[minnesota750]

I'm going through the engine on a 73, and need crank and rod bearings. The casing numbers are all 5s and the journal numbers are 2,2,3,2. Based on the formula in the manual that makes the numbers needed 3,3,2,3 - but how does that translate into part numbers. Any help would be greatly appreciated.
Thanks.

Wanted to share the response from the engine section where I also posted this question :

«if you go to a parts site like partspitstop.com you will find bearing numbers for the con rod and main bearings.


The number 1 bearing as per your service manual chart will be the first item listed ending in 00
The number 2 bearing as per your service manual chart will be the second item listed ending in 10 and so on
«If your magic numbers are 2 and 3 your bearing part numbers will end in 10 and 20»


I hope that helps, I am presently in the middle of rebuilding two engines so «i have done the research.

In some service manuals there is a false information in Bearing 4 center thickness tolerance numbers. See correction.

In my pic there are also part numbers according to bearing numbers.



Crankshaft
Bearing 1    341-11416-00
Bearing 2    341-11416-10
Bearing 3    341-11416-20
Bearing 4    341-11416-30
Bearing 5    341-11416-40

Con rod
Bearing 1    341-11656-00
Bearing 2    341-11656-10
Bearing 3    341-11656-20
